(CNN) - Stumping for Sen. Barack Obama, Sen. John Kerry faces a unique challenge when it comes to taking on the presumptive Republican nominee.
That's because Sen. John McCain has said that Kerry, in 2004, "asked if I would consider being his running mate." McCain told reporters earlier this month that at the time of the conversation, he made clear to Kerry the answer was no.
Kerry has said McCain's representatives contacted him about the possibility, and both men say there was never an actual offer.
McCain went on to campaign aggressively for President Bush in 2004.
Still, the complexity adds an unusual wrinkle for times like Sunday, when Kerry takes on McCain.
"Hillary Clinton has every right in the world to continue to fight, but the important thing is to be fighting against John McCain," Kerry told ABC's "This Week," discussing some calls for Sen. Clinton to drop out of the race.
"It is very important for both people to keep the eye on the real target - John McCain and the Republican disaster of the last seven and a half years," he added.
As the 2004 Democratic presidential nominee, Kerry is one of Obama's most prominent campaign surrogates.

Senator Kerry is correct.
Kerry still thinks he has some influence.
John Kerry will not help Obama. Obama did not him because he will mispeak and create problem for him.
Kerry was a tool and is a tool and always will be a tool
John Kerry, John McCain, Mitt Romney, Barack Obama. It seems everyone EXCEPT Clinton is focused on the issues.
Clinton and Obama both should be alot more worried about McCain than one another. At this point they have driven alot of people like myself whom are Democrates, to throw up thier hands and consider voting for McCain.
Commander in chief McSame doesn't care that we spend billions of dollars in other countries, 40 million people without health care, and that inflation and shipping jobs overseas is on the rise.
Hillary wore the same suit my Uncle Fred wore at the family reunion.
I do not recall
no new taxes
I need a nap
Kerry is a man that I can believe in. I feel he made the right choice and Obama has the right people in his corner. Hillary has the Gov of PA who in the 80's almost went to jail for doing the same thing that the Clinton's are known for. Picking people who have too many scandals.
Kerry obviously has to attack McCain, because the candidate that he supports has no record. If Obama had any record, Kerry would highlight that record instead of attacking McCain.
Who cares about John Kerry? He is a big loser. On top of that, his state voted overwhemlingly for Hillary, yet he is a superdelegate supporting Obama. Then, he turns around and tells other superdelegates go to with what their state voted for.
Senator Kerry is correct in his statemant about "Mc Bush". The right wing nuts (Republicans) have destroyed our reputation in the world. Hopefully the Dems ( I mean Obama) can win and restore some moral authority the United States use too have. Moreover, the media need to get off of this Rev. Wright business. Least you forget, Ronald Reagan made his 1980 Presidential announcement in Phildelphia, Mississippi. He said some pretty racy some. Does any one remember that. It's unbelieveable that Senator Obama have to defend someone elses statement and not his own. Come on CNN, I except better from you guys. Please don't make this a double standard campagin. I guess Ferarro & Hillary, can get away with it.
I want to see as thorough a going-over of McCain's military
record and background as we got about Kerry's. Swift boats
and all. No sugar coating or cover-ups.
